Power Supply; Ac Input; Dc Outputs; Maximum Rated Output Power - NCR RealPOS 70XRT User Manual

Power Supply

The power supply provides power to the 7403 Terminal, as well as various retail
peripherals through the powered connectors. The power supply is controlled by a
logical on/off switch, which permits it to be disabled through software.
Other features include:
•
•
Functionally, the terminal's ON/OFF switch controls the power supply control logic to
activate the power supply. This switch does not control actual AC mains voltage
applied to the power supply.

AC Input

The power supply operates with the following voltage ranges.

DC Outputs

The power supply has the following DC outputs:

Note: The total continuous output power for all rails (3.3V, 5V, 12V, -12V, 5VSB, 24V)
should not exceed 265W.

Maximum Rated Output Power

The maximum rated output power as defined as the continuous load is 265W.
However, in the 7403, this power supply will be limited to supporting around 200W,
to minimize thermal impact to the system.
